Brittas Castle probably dates from the late 1200s.2 It sits on the left bank of the river Mulcair, and was a chief seat of de Burgh or Burke of Clanwilliam later lord barons of Brittas.

Brittas was described as once being ‘a castle of considerable strength and extent’, with a massive keep with an enclosed courtyard and ‘with flanking towers at the angles’.3

Two towers, one lower to the east of the larger tower, are shown on the 17th-century Down Survey maps.


At the end of the 19th century, large sections of the court-walls were extant; but the interior of the castle had by then been fairly gutted.

At present, only broken sections of the court wall are visible, but the main tower is (externally) in a relatively strong state or repair.


The castle lies on a working farm. Permission is required.
